MRS Summary: MRS-R01A is identified as a buffer area used during artillery training.

Ricochet Area (FTIG-003-R-01)

Fort Indiantown Gap (FIG)

Army National Guard

Media Evaluated ("X" all that apply):

Groundwater

Surface soil

Sediment (ecological receptor)

Current receptors include recreational users (e.g., hunters, hikers), trail maintenance personnel, firefighters, environmental field personnel, and PGC personnel and contractors.

Future receptors might also include construction workers (Section 8.1.2.4 of the Final Remedial Investigation - Weston, 2011).

The Ricochet Area MRS has been characterized through an understanding of the historical information and a thorough field investigation during the Remedial Investigation.

From an evaluation of the RI data and predictive density calculations, the Ricochet Area MRS footprint was subdivided into two MRSs: (1) Ricochet Area MRS, comprised of

the area from the ridgeline of Second Mountain to Stony Creek and the former Cold Spring Firing Point; and (2) Sharp Mountain MRS, comprised of the area from Stony Creek

to the ridgeline of Sharp Mountain (Section 8 of the Final Remedial Investigation - Weston, 2011). The Ricochet Area encompasses 3,262 acres and is located entirely on

property owned by the Pennsylvanina Game Commission, immediately adjacent to and north of FIG. There are historical ranges that potentially had safety danger zones

(SDZs) or safety waivers that extended into the Ricochet Area MRS. Historical ranges are typically in the same area as current ranges; however, no current ranges have SDZs

that extend beyond the installation boundary (Section 8 of the Final Remedial Investigation - Weston, 2011).

Description of Pathways for Human and Ecological Receptors:

The MEC exposure pathway for human receptors is direct contact through handling (e.g., picking up the item) or unintentional disturbance (e.g., hitting item during

construction activities). The MC exposure pathway for human receptors is associated with direct contact through incidental soil ingestion, dermal absorption of soil, and

inhalation of airborne particulates. The MC exposure pathway for ecological receptors is primarily associated with direct contact and uptake (plants) or ingestion of soil.

Indirect exposure pathways exist for herbivorous small mammals (i.e., dietary exposure to plants) and insectivorous and carnivorous birds and mammals through trophic

transfer (Sections 1 and 6 of the Final Remedial Investigation - Weston, 2011).

MRS Background Information

DIRECTIONS: Record the background information below for the MRS to be evaluated. Much of this information is available from Service and DoD databases. If the MRS is

located on a FUDS property, the suitable FUDS property information should be substituted. In the MRS Summary, briefly describe the UXO, DMM, or MC that are known or

suspected to be present, the exposure setting (the MRS's physical environment), any other incidental nonmunitions-related contaminants (e.g., benzene, trichloroethylene)

found at the MRS, and any potentially exposed human and ecological receptors. If possible, include a map of the MRS.

SOURCE OF HAZARD 10




DIRECTIONS: Document any MRS-specific data used in selecting the Source of Hazard classifications in the space provided.

Although the Ricochet Area MRS never served as an impact area or was intentionally fired into the area was implied by ricochets from FIG

impact area and over/under shots from FIG and Cold Springs Firing Point. During the field investigations Cold Spring Firing Point was

identified by the discovery of DMM. The recovery of DMM (4-MK-2A4 primers) and firing point debris (e.g., fuze shipping containers,

155mm rotating band covers and 155mm lifting lugs) at the former Cold Spring Reservation confirms the location of the former Cold Spring

Firing Point (Final Remedial Investigation Report, Section 6, Weston, 2011).

DIRECTIONS: Document any MRS-specific data used in selecting the Ecological and/or Cultural Resources classification in the space

provided.

Many prehistoric and historical archaeological cultural resources are located within the Ricochet Area MRS footprint. In cooperation with the

Pennsylvania State Historic Preservation Office (SHPO), field personnel avoided conducting field activities within identified areas of

significant historical and/or cultural significance and followed the procedure outlined in the flow chart for Inadvertent Discovery of Cultural

Remains (Appendix M of the Final Work Plan). The American holly is the easiest plant to identify based on physical appearance year round.

The netted chainfern was not immediately recognizable in early spring 2010 activities. Minniebush also has a late spring budding process,

which makes visual recognition by the untrained eye difficult. No netted chainfern or minniebush were observed during the RI. A diverse mix

of mammals, birds, reptiles, amphibians, insects, and benthic macroinvertebrates is supported by the habitat of the Ricochet Area MRS.

Commonly observed species at the site were white-tailed deer (Odocoileus virginianus), Eastern wild turkey (Meleagris gallopavo silvestris),

and ruffed grouse (Bonasa umbellus). Timber rattlesnakes (Crotalus horridus) were commonly found among the scattered boulder areas of the

site. Stony Creek is routinely stocked with the following fish species: rainbow trout (Oncorhynchus mykiss), brown trout (Salmo trutta), and

brook trout (Salvelinus fontinalis). (Final Remedial Investigation Report, Sections 3.6 and 3.7, Weston, 2011).

MRS Background Information

DIRECTIONS: Record the background information below for the MRS to be evaluated. Much of this information is available from Service and DoD databases. If the MRS is located on a FUDS property, the suitable FUDS property information should be substituted. In the MRS Summary, briefly describe the UXO, DMM, or MC that are known or suspected to be present, the exposure setting (the MRS's physical environment), any other incidental nonmunitions-related contaminants (e.g., benzene, trichloroethylene) found at the MRS, and any potentially exposed human and ecological receptors. If possible, include a map of the MRS.

Current receptors include recreational users (e.g., hunters, hikers), trail maintenance personnel, firefighters, environmental field personnel, and PGC personnel and contractors. Future receptors might also include construction workers (Section 8.1.2.4 of the Final Remedial Investigation - Weston, 2011).

The Ricochet Area MRS has been characterized through an understanding of the historical information and a thorough field investigation during the Remedial Investigation. From an evaluation of the RI data and predictive density calculations, the Ricochet Area MRS footprint was subdivided into two MRSs: (1) Ricochet Area MRS, comprised of the area from the ridgeline of Second Mountain to Stony Creek and the former Cold Spring Firing Point; and (2) Sharp Mountain MRS, comprised of the area from Stony Creek to the ridgeline of Sharp Mountain (Section 8 of the Final Remedial Investigation - Weston, 2011).

The Sharp Mountain MRS encompasses 4,740 acres and is located entirely on property owned by the Pennsylvanina Game Commission, immediately adjacent to and north of FIG. Sharp Mountain MRS corresponds to the remaining area where there is no indication of munitions activities or a potential of UXO/DMM. This MRS is considered a separate MRS for acreage accounting purposes only, so that all acreage is accounted for in the Army’s database (Section 8 of the Final Remedial Investigation - Weston, 2011).

Description of Pathways for Human and Ecological Receptors:The MEC exposure pathway for human receptors is direct contact through handling (e.g., picking up the item) or unintentional disturbance (e.g., hitting item during construction activities). The MC exposure pathway for human receptors is associated with direct contact through incidental soil ingestion, dermal absorption of soil, and inhalation of airborne particulates. The MC exposure pathway for ecological receptors is primarily associated with direct contact and uptake (plants) or ingestion of soil. Indirect exposure pathways exist for herbivorous small mammals (i.e., dietary exposure to plants) and insectivorous and carnivorous birds and mammals through trophic transfer (Sections 1 and 6 of the Final Remedial Investigation - Weston, 2011).

Description of Receptors (Human and Ecological):

MRS Description: Describe the munitions-related activities that occurred at the installation, the dates of operation, and the UXO, DMM, or MC known or suspected to be present. When possible, identify munitions, CWM, and MC by type:

Contaminant Hazard Factor (CHF)DIRECTIONS: Record the maximum concentrations of all contaminants in the MRS's surface water and their comparison values (from Appendix B of the Primer) in the table below. Additional contaminants can be recorded on Table 27. Calculate and record the ratios for each contaminant by dividing the maximum concentration by the comparison value. Determine the CHF by adding the contaminant ratios together, including any additional surface water contaminants recorded on Table 27. Based on the CHF, use the CHF Scale to determine and record the CHF Value. If there is no known or suspected MC hazard with human endpoints present in the surface water, select the box at the bottom of the table.

DIRECTIONS: Only use this table if there are more than five contaminants in any given medium present at the MRS. This is a supplemental table designed to hold information about

contaminants that do not fit in the previous tables. Indicate the media in which these contaminants are present. Then record all contaminants, their maximum concentrations and their comparison

values (from Appendix B of the Primer) in the table below. Calculate and record the ratio for each contaminant by dividing the maximum concentration by the comparison value. Determine the

CHF for each medium on the appropriate media-specific tables.

DIRECTIONS: In the chart below, enter the letter rating for each module recorded in Table 10 (EHE), Table 20 (CHE), and Table 28 (HHE). Enter the corresponding numerical priority for each module. If information to determine the module rating is not available, choose the appropriate alternative module rating. The MRS priority is the single highest priority; record this relative priority in the MRS Priority or Alternative MRS Rating at the bottom of the table.

NOTE: An MRS assigned Priority 1 has the highest relative priority; an MRS assigned Priority 8 has the lowest relative priority. Only an MRS with CWM known or suspected to be present can be assigned Priority 1; an MRS that has CWM known or suspected to be present cannot be assigned Priority 8.
